=====Common hardware specifications=====
* Processor: Zilog Z80A microprocessor clocked at 3.5469MHz.
64kB ROM. 2×32kB EPROM arranged in 4 pages of 16kB.* RAM: 128kB of Dynamic RAM, arranged in 8 pages of 16kB.
* Graphics: 256×192 pixels, 16 colours, attribute based. See [[Spectrum Video Modes]].
* Sound: AY-3-8912 3 channel, 8 octave Programmable Sound Generator and "beeper". Modulated onto video signal.
The memory space is divided into four
16kB pages and can be used in two ways; "Standard paging mode" and "Special paging mode".
Paging is controlled by performing I/O writes to ports 0x1ffd and 0x7ffd.
====Standard paging mode====
64kB of ROM and 128kB of RAM can be paged into the memory space as shown in the diagram below:
